Abstract: A transfer case (12) for distributing a driving torque of an input shaft (19) between two drivable output shafts (22, 29) is described. The transfer case (12) is realized with two controllable and adjustable frictionally engaged clutches (k_VA, k_HA), which are arranged between the input shaft (19) and the output shafts (22, 29) and whose transfer capabilities can be respectively adjusted via separate actuating devices (10, 11). A driving torque can be distributed between the drivable output torques (22, 29) in dependence upon the set transfer capabilities of the clutches (k_VA, k_HA). One clutch (k_HA) can also be radially enclosed by the other clutch (k_VA).

The cross-shafts being actively connected via a transverse distributor gear and being driven by the engine. The vehicle also possibly having a second vehicle axle with at least two wheels. Frictional shift elements of the first vehicle axle, between the wheels of the first vehicle axle and the transverse distributor gear, are provided for variable distribution, to the first vehicle axle, of the fraction of the drive torque from the engine in the transverse direction of the vehicle between the two wheels. A desired yaw torque is determined. The drive engine, brake system and shift elements are controlled such that the desired yaw torque is produced essentially without changing the positive forward drive of the vehicle.

The first clutch (k_VA) is placed between the main transmission (3) and the first vehicle axle (4) and the second clutch (k_HA_L) and the third clutches (k_HA_R) are respectively located between an axle transmission (7) and two driven wheels (5A, 5B) of the second vehicle axle (5). The respective transfer capabilities of the clutches (k_VA, k_HA_L, k_HA_R) can be adjusted with an actuator (8), and the driving torque between the driven vehicle axles (4, 5) can be distributed depending on the adjusted transfer capabilities of the clutches (k_VA, k_HA_L, k_HA_R).

Abstract: A transmission for distributing a drive torque to two drive output shafts, with two planetary gearsets each having at least three shafts. A respective shaft of a planetary gearset is connected to a drive input shaft. Furthermore, one shaft of each planetary gearset constitutes one of the output shafts and in each case at least one further shaft of a planetary gearset is connected with a shaft of another planetary gearset. An operation-status-dependent torque of one shaft can be supported by the connection, depending on an operating status of the other shaft connected thereto, in such manner that when there is a rotation speed difference between the output shafts, a speed-difference-changing torque is applied to the planetary gearsets. Furthermore, a drive train is proposed, in which a drive torque from a drive-power-source is distributed variably in the longitudinal and transverse direction of the vehicle in an operation-status-dependent manner.

An electric motor (10), a gear train (11) functionally associated with the electric motor (10), and a driving-converter (12) situated between the shifting element (k_VA, k_HA_L, k_HA_R) and the gear train (11), by way of which the rotary motion of the electric motor (10) is transformed into a translatory, activation motion for the control of the shifting element (k_VA, k_HA_L, k_HA_R), are all provided in order to vary the power-transfer capability of the shifting element (k_VA, k_HA_L, k_HA_R) within the limits of the control state of the drive-converter (12).

Abstract: A transmission for distributing a drive torque between at least two drive output shafts with at least two planetary gearsets, each having at least three-shafts. In each case, a shaft of a planetary gearset is connected to a drive input shaft and a second respective shaft of a planetary gearsets is the drive output shafts. A respective third shaft of the planetary gearsets communicates with a brake such that a degree of distribution of the drive torque between the two output shafts varies as a function of the transfer capacities of the brakes. A transmission device controls and regulates a drive torque from a drive engine between the two output shafts of the transmission device. The transfer capacities of the two brakes are adjusted such that one brake is in a synchronous condition and the transfer capacity of the other brake is varied between a lower and an upper limiting value.

Abstract: A method for determining a control standard of an active steering device (10) of a vehicle (1) controllable by a control device (11). A driving dynamic of the vehicle (1) is influenced according to the control standard. The control standard is determined according to a nominal yawing rate calculated at least with reference to different actual operating parameters of the vehicle and one dynamic vehicle state determined according to the nominal yawing rate and actual operating state parameters. The control standard is superimposed on a steering transit angle preset by a driver so that an existing actual yawing rate is changed in direction of the nominal yawing rate.
